CVE-2016-3726 (Jenkins SECURITY-276) is an open redirect vulnerability in Jenkins before 2.3 and Jenkins LTS before 1.651.2. Certain Jenkins URL-handling paths insufficiently validate redirect targets, permitting attacker-crafted links containing scheme-relative URLs to redirect a user to an arbitrary external website. The weakness can support phishing and other redirect-based social-engineering attacks.
